The question makes no sense as such. You'd have to tell us the purpose
you want to achieve with partitioning. Depending on that, you'd choose
the partitioning strategy and the partitioning key.
At any rate, you'll probably have to drop the foreign key constraint
unless your partitioning key is "id".
